I'm bi and I suck at talking to girls?

Lot of people say if it doesn't come natural then ur strsstra BUT I suck at talking to guys to and it's easier to wait for them to come to you but with girls it's always a guessing game I like super female girls and you never know unless you ask and if there not intoi girls it's awkward Since I'm not aggressive enough to approach or ask I've been limited to girls who do apporch me and that's studs (pass) and girl with bfs (sometimes... Don't judge)But I want a sexy girlfriendPlease give me tips
